REFRIGERATOR CONSTRUCTION.

Application led July 2,

To all 'whom z't may concern: y

Be it known that l, REUBEN E. OTTEN- HEIMER, a citizen of the United States, residing at Baltimore city, State of Maryland, have invented certainl new and useful lmprovements in Refrigerator Construction, of which the following is a specification.

This invention relates to refrigerator construction and more especially to the con struction of the door jambs whereby leakage of air between the timbers forming the jambs is guarded against effectually.

One of the objects of the invention is to form a jamb of cooperating stepped sections which, when assembled, contact along tortuous lines so as to provide the maximum resistance to the How of air between the sections.

A further object is to provide means for drawin the sections together to hold their steppa faces tightly in contact.

"ll ith the foregoing and other objects in view which will appear as the description proceeds, the invention consists of certain novel details of construction and combinations of parts which will be hereinafter more fully described and pointed out in the claims, it being understood that various changes may be made in the construction and arrangement of the parts without departing from the spirit of' the invention as claimed.

lin the accompanying drawing, which is a sectional perspective view of a portion of a refrigerator, the preferred form of the invention has been shown.

Referring to the drawin by characters of reference, A designates te stationary or wall section of the jamb and B designates the adjustable and removable section. The

section A includes a face strip 1 to the inner face of which are secured parallel spacing stri s 2 and 3 and a bearing strip t. The strips 2 and d are in contact and interposed between the strips 2, 3 and d and the face strip 1 is a layer of suitable insulating material such as one or more sheets of paper 5. An air space 6 is provided between the strips 2 and 3 and a strip 7 of fibre insulation is also interposed between said strips. Secured to the strips 2 and 3 and bridging the space 6 is a sheet 8 ot aper or other suitable insulatin material. paced strips 9 are secured te t e stri s 2 and d and upon the sheet 8 and one or t ese strips 9 constitutes a bearing er step of the 1923. Serial No. 649,084.

section A. An inner face strip 10 is secured to the strips 9 and is spaced therefrom by a layer 11 of paper or other suitable insulatin material. This strip 10 also constitutes a earing or step of thesection A and projectsbeyond the alined outer sides of strips 3 and 9 so as to extend into a side finishing strip 12 that is secured to the strips 1, 3 and 10.l

The other section, B, of the jamb includes a face strip 13, a beveled abutment strip or wear strip 14 and a stop strip 15 projecting from the inner marginal portion of the abutment strip. In the angle formed by the strips 13 and 14 is secured a group of bearing strips 16, 17 and 18 providing steps,

as shown and an inner face strip 19 is secured to the abutment strip 14 and the stop strip 15 and provides an additional step, as shown. A bead strip 20 can be secured to .this strip 19 to provide a finish.

A desired number of openings 21 are formed in strip 1 to receive the heads of bolts 22 that are extended through the strip 4f and into the strips 17. means of the bolts the section B can be drawn tightly against the section A so that the steps of one section will rest against the steps of the other section and a tight connection provided between the parts. A finishing strip 23 can be secured to strip 1 for the purpose of concealing the bolt holes 21. By removing the bolts or screws 22 the section B can be removed bodil for repairing or re lacing the parts. he meeting stepped aces of the sections held together tightly prevents leakage of air through the jamb structure and adds materially tothe eiliciency of the refrigerator.

What is claimed is 1. lin a refrigerator .construction a door jamb including a stationa section hav- Obviously by ing a stepped face, a remova le section hav- A ing-a stepped face means for drawing together the stepped faces of the two sec-= tions and holding them in contact.

2. ln a refrigerator construction a door jamb including a stationary section having a stepped face, a' movable section having a stepped face, means for drawing together the stepped tac-es ot the two sections, and a nishing strip for concealing said means.

3. lin a refrigerator construction a deer jamb including a stationary section ceinprising a tace strip, spacing and hearing litt@ lill@ strips secured thereto and insulated therefrom, there being an air space between the spacing strips, additional spacing strips, secured to and insulated from the first named spacing strips, and an inner face strip secured to and insulated from the second-mentioned spacing strips, and a movable section including a face strip, an abutment strip secured thereto, a stop strip upon the levata? abutment str1 and stepped strips secured in the angle oi) the face and abutment strips, and means carried by the stationary section and enga ing the movable section, for

drawing toget er the stepped faces of the sections.

In testimony whereof affix my signature.
